PHP error and irrelevant Slugs metabox in custom admin pages

[yoancutillas]

Hello,

The Slugs module causes a PHP error on any admin pages using metaboxes if they are not a WP_Post: qtranslate-xt\modules\slugs\admin\slugs-admin.php line 130

The reason is that the Slugs module assumes that the passed variable $post is a WP_Post object. Of course, a page displaying metaboxes isn't necessarily a WP_Post.

A workaround would be to exit the qts_draw_meta_box() function early if the passed variable isn't a WP_Post. For example, by adding at line 124: if( ! ( is_object( $post ) && ! empty( $post->ID ) ) ) { return; }

A better solution would be to not display the "Slugs per language" metabox at all on irrelevant pages (that is, on pages that are not WP_Post).
